installation guide: The supplied ISO DIN Adapter is simply installed between the radio and the original wiring for all stereos with DIN ISO Connection. sound2car can also be installed behind the glove compartment: In this case, remove the glove compartment (usually fastened with four screws) and the radio from the console. Run the DIN ISO adapter cable from the stereo slot behind the glove compartment. Attach all cables in accordance with the following installation instructions. Ensure that the housing of sound2car does not rest directly against the vehicle frame so that vibration cannot be transmitted to the equipment. If necessary, fit foam material between the parts. Please ensure that the heat can escape unhindered. Connecting DIN-ISO Adapter: Remove the stereo from the console. Remove DIN ISO plug from the vehicle wiring harness at the rear of your stereo Insert the supplied DIN ISO Adapter between the stereo sockets and the vehicle wiring harness If your vehicle does not have ISO connectors, our accessory program can supply suitable auxiliary adapters for your vehicle: +12 V?? Because the pin connections for continuous power and ignition are not identical across vehicle types, the flat connectors allow the correct connections to be made. In order to be able to use all functions of sound2car the unit should be connected to the permanent plus, therefor connect the two yellow cables the PIN 24 of the system plug with the yellow cable of the ISO- Adapter. Test the functionality Insert the navi-charger cable in the 12V-connector of the ISO-Adapter socket. The charger cable should now be supplied with power (check if the LED of the charger plug is illuminated). If the charger has no power, then connect the yellow cable from sound2car (PIN 24) with the red cable of the ISO-Adapter. Test the functionality of the Navi charger cable again. 3
Tip: Auto Power Function Connect sound2car to the continuous plus to use the Auto Power function. When the stereo is switched on, it will be activated automatically. After switching off the stereo or after the last audio output, all functions remain available for about 45 minutes. After this, sound2car will switch into quiescent mode, which will avoid discharging the battery. The 12V output for navi-charger cable is also controlled by AutoPower-function. If sound2car is not used in conjunction with a standard stereo, then the ignition signal can be used to activate the functionality. The switch-off delay functions in addition to the ignition signal. For this configuration, the +12V continuous plus is connected to PIN 24 (yellow) and, in addition, the +12V ignition plus is connected to PIN 22 (red). Tip: Dynamic Loudspeaker Control To use the dynamic loudspeaker control of sound2car, the mute signal must NOT be connected to the stereo (flat connectors white/yellow, white/brown stay open). Navigation announcements are given out over the front speakers while the rear speakers play e.g. music, news or traffic announcements. While MP3 audio is given out by sound2car the rear loudspeakers automatically stay activated (Long-Time-Mode) Usage of mute signal: The activity of the mute signal can be adjusted as desired. There is a jumper on the board to set the function. POSITION 1: The mute signal is immediately activated when an audio signal is recognized. (eg if you want to mute the rear speakers during the Navigation announcement) POSITION 2: The mute signal is activated only in the long-time mode. (e.g. if the so-called center speaker is installed in the vehicle, you can use this function to mute all speakers which are not managed over sound2car) Because the pin connection for mute is not identical across vehicle types, the flat connectors allow the correct connections to be made. Connect cable white/brown (PIN 19) to cable white/brown, or Connect cable white/brown (PIN 19) to cable white/yellow. (Note: Observe the correct pin connection for the mute signal of the stereo. The layout of stereo connections can be different from the standard). Connection PDA/PNA and ISO Plug the charger cable of the PDA/PNA into the connector socket of the ISO- Adapter cable Tip: 12 V Socket for the Navi Charger Cable The sound2car provides a connector socket with a screened supply (+12V) for the connection of navi-charger cables. This power supply is specifically designed for the connection of your vehicle navi charger cable. Because of the various shapes of the charger plugs, it is possible that, during driving, the plug becomes loose; therefore it is recommended that the plug should be secured to the socket with adhesive tape. The charger cable of the navi must not be modified. The navi must not be connected directly (without charger plug) to the socket. Note: The 12V output for navi-charger cable is also controlled by AutoPower-function of sound2car. 4
Connecting Audio Equipment (PNA, PDA, PPC, MP3-Player, etc) sound2car is equipped with two 3.5mm jack sockets for connecting audio sources. The two sockets can be found near the ISO-Adapter socket and are marked as Audio-IN 1 and 2 (suitable jack plugs can be found in our catalog). If both audio sources are played simultaneously into both inputs (e.g. MP3-Player and Navi), both audio signals will be mixed together. Note that if you supply your own cables and plugs, they must follow the diagram shown here. NOTE: Mono-jack connectors (2-core) cannot be used. Functional test After installing sound2car as described, you can begin to test the functionality. If you have chosen the continuous plus connection, the sound2car switches on automatically when the stereo is switched on. For operation on ignition plus, sound2car switches on when the ignition is switched on. When the stereo (where the ignition is in the appropriate position) is switched on, the operating light ( EIN/ON ) next to the ISO connector socket plug will illuminate. The stereo should continue to be heard on all loudspeaker channels. Now, test the output from sound2car: Set the output volume level of the audio source (Navi, MP3 etc) to about 60-70% (The value depends on the audio source) and then start the output. You should now hear the output of the external audio source on both front loudspeakers. You should continue to hear the stereo/cd on the rear loudspeakers. After continuous audio output of around 20 seconds, the rear loudspeakers will switch to the sound2car output. The equipment is now in Long Time Mode and the delay to switch the relay back to stereo is extended to about 20 seconds, to bridge any quiet passages or pauses in the music output 5
Audio Trigger (Threshold) Level Adjustment: The circuit has an adjustable trigger level. If sound2car is activated without a specific audio signal input, then the trigger level can be changed to reduce the sensitivity. The volume level of the audio source should be set to around 60-80%. To the left of the ISO-System connector, you will find the trimmer adjustment Mute Offset for the trigger level. Adjust the trimmer to raise the trigger level (turn to the right), until the mute signal is no longer triggered without an audio input. If the audio output via sound2car is interrupted, then the trigger level should be reduced (turn to the left), or the volume of the audio source should be increased. Use a small screwdriver to adjust the output level of the internal volume control or plug in an external volume level controller (optional) If the output level of sound2car needs to be slightly louder than the normal level, you can fine-tune the levels of the audio sources to the respective audio environments. If the adjustment range of the audio source is not wide enough then you should use an external volume controller. This is ideal for widely different acoustic levels e.g. Camperwagons, Transporters, and Convertibles etc. After switching off the stereo (where appropriate, the ignition position off), the sound2car remains active for about 40 minutes. A new switch on or audio output signal resets the delay time and the equipment remains active for a further 40 minutes. If the stereo is switched off during the drive, sound2car continues to function without limits until the end of the switch-off delay time or another audio signal is recognised. When the switch-off delay time has expired, then the equipment goes into quiescent mode to avoid draining the battery. Check that the sound2car power indicator switches off after about 40 minutes as programmed.

Block Diagram Exteral Volume-Control The volume control allows to change the playback volume of sound2car by an external body. Especially in ambients with changing noise (such as cabriolets, campers or vans) it is ideal, because the volume of the navigation announcements or other audio sources can always be tailored to personal needs.
